I recently replaced my Circuit Opening Relay and ever since my fuel gauge does not work. I had removed the vehicle's computer to inspect during this fix and suspect this is the cause of the fuel gauge not working . Is there a way to reprogram the computer to fix this? Also , I have been getting a fairly strong vibration while accelerating. Could the firing sequence be off because of the computer removal? Rig runs strong with no apparent hesitation so I am wondering if this vibration could be an engine issue or something completely unrelated , perhaps alignment ? Thank You !

 

I just discovered the rear u joint on my drive shaft is loose with a good deal of wobble, thinking this is my vibration problem.
